FEED-MIXING DEVICE.

Application filed February 15, 1923.

vmore particularly to a mixing device which may be easily and quickly manipulated to thoroughly mix the grains and other feed,

'capable of being used in the home.

My object is the provision of a simple inexpensive device of this nature by which the desired result can be obtained in an effective efficient manner as well as conveniently and with minimum effort and trouble.

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure 1 is a side elevation of my improved device,

Figure 2 is a vertical longitudinal section therethrough,

Figure 3 is a top plan view,

Figure e is a detail perspective view of one of the partition plates, and

Figure 5 is a side view partly in section, and upon a reduced scale, illustrating a slightly modified form.

Referring now to these figures my invention proposes a device includinga vertically disposed mixing box and a horizontaly disposed feed box 11, both of said boxes forming parts of a rigid frame incuding front uprights 12 formed of any suitable material as, for instance, angle iron and intermediate uprights 13 which may also be formed of angle iron. In this frame the feed box 11 is supported in elevated position with its upper portion open to receive feed to be mixed, which is preferably introduced therein, in layers. At one end this feed box 11 opens into and communicates with the upper portion of the mixing box 10, the upper portions of the intermediate uprights 13 extending vertically at opposite sides of this mentioned end of the feed box so that these said upper portions of the intermediate uprights 13 form stops for partition plates 14 adapted to extend transversely of and slidably interfit the feed box 11 at various points between its discharge end in communication with the mixing box,

and its follower or feed plate 15 which also slidaby interfits the same and is movable for the full length of the feed box toward its discharge end by virtue of flexible connections 16 secured at one end thereto and having their opposite ends con-A nected to a winding drum 17. This drum is secured upon a shaft 18 mounted transversely through the mixing box 10 and provided at one outer end with a crank 19 by which it may be rotated, and with a ratchet wheel 2O with which a dog 21 is engagable to prevent movement of the follower or feed plate 15 in an outward direction within the feed box except when it is desired to d0 so preparatory to a refilling of the feed box. In order to permit of passage of the flexible connections 16, it will be noted .that each of the partition plates 14, in addition to an upper slot 22 affording a hand hold, may have vertical side slot-s 23 through which the connections extend although it is apparent these slots maybe dispensed with and the flexible connections extended along the side walls at the side edges of the partition plates. It is obvious that in the feed movement each partition plate when positioned at the discharge end of the feed box and when in engagement with the stops formed by the upper portions of the intermediate uprights 13, becomes a feed cut off which checks the movement of material from the feed box into the mixing box and thus the several feed plates measure the feed into separate charges for the mixing boxY and each plate in turn checks further feed into the mixing box until it is removed.

In the lower portion of the mixing box 10 is a mixed feed bin 24, which may be in tegral therewith or removable therefron'i as shown, and which is in either instance provided at its outer side with an inclined scoop board 25 and is positioned beneath the semicylindrical base 2G of the mixing chamber within the latter of which a mixing wheel is mounted on a shaft 27 rotatable immediately above the chamber base 26. This base 26 of the mixing chamber has a discharge slot 28, at opposite sides of which are guides 29 adapted to slidably receive the side edges of a discharge plate 30, shiftable inwardly through one side wall of the mixing box 10 as indicated in Figure 1 and provided, as shown in this ligure with a handle 51 by means of which it may be readily inserted and wi hdrawn, in the latter instance permitting of the fall of mixed grain from the mixing chamber into the bin 2a.

The mixing wheel is preferably formed of a pair of end plates 32 to which are rigidlyv secured the ends of a` peripheral series of blades 33 `preferably of the angular forni shown, these blades forming mix ing paddles, and the mixing wheel lshaft 27 is journaled through the side walls of the mixing box Vl() and provided one end lwith a crank 27 by means of which it may be readily and easily rotated.

Thus in operation the follower or feed plate l5 is shifted to the outer end of the v feed box ll in the position shown in yFigure 2 and one at least of the partition plates le is inserted at the inner discharge end of i the feed b ox vagainst the stops for ied by the upper ends of the intermediate pai-'titions @ther -partition plates le may be inserted at spaced points as seen in yFigure 2 order to divide the feed box, each checking the feed as it comes into engagement 'with the upper ends of the intermediate upriglits.

The materials to vbe mixed are then introduced into the feed box and spread out in superposed layers between the feed plates 4and between the rearmost feed plate and the follower l5, after which the first partiton plate that is the one against the upper portions of the intermediate uprights is re moved and the crank 19 rotated so as to drawthe follower or feed plate l5 toward the inner .discharge end of the feed box until the next feed plate le comes into engagement with the stops formed by the upper portions of the intermediate uprights. For further feed this plate must then be ren'ioved. At the saine time the mixing wheel is rotated by means of its crank 2P, in either a clockwise or counter-,clockwise d'recticn dependent upon the angularity of the blades so that as the material falls into the feed chamber through the open discliarge end of the feed box, the vmaterial will be caught, and thoroughly intermixed before it falls rto the base of theV mixing chamber. Upon withdrawal of the discharge slde the materials so mixed will fall into the bin 2li, from which they may Ibe withdrawn either. by means of a scoop thrust inwardly upon the scoop board 25, or by tirstreinserting the feed slide ,30 and bodily removing' th'e bin 24 from the lower portion ofthe mixing box.

Instead of the partition plates 14 may use a simple feed control gate between the feed box ll and the mixing box lO7 of any suitable construction, and which may take the form shown in Figure 5. ln this figure a feed control gate is shown conssting of a vertical se y'ies of spaced, parallel cross s capable of proven g Ythe fall of rial under normal conditions, and at the saine time providing `for ready movement of material between the said cross plates .vhen the follower is drawn forwardly. l

It is Vobvious from the foregoing that the device proposed by my invention is simple 'and economical both vas toffirstleost' and uplreep and it is further 'obvious that itV ject at their upper portions along' opposite of the discharge end of the 'feed box toA form stops, a feed plate shiftable lengthwise of the feed box, and partition plates insertaljile within the feed box and mov-able therein against the said stops.

2. A. feed mixer incliu'linc` an upright mixing 'box having a mixing chamber and a mixing device within Vsaid chamber, a -feed box in communication at one end with the upper portion of the mixing box, a frame of which the mixing and feed boxes'form parts, having u prlghts certain of which project their upper portions along opposite sides of the discharge end of the :feed'box to forinstops, a feed plate disposed within and shiftahle vlengthwise of the feed box, flexible connections extendingffroni said feed plate through the feed tbox and into the upper portion of the mixing box, `aavintLling'drum journaled in the upper portion of the feed box for said flexible connectionsJ having a crank, and partition pla-tes for disposition witiiin the feed box, movable there in against said stops, and having vertical slots through which the gliexible connections extend.

3. A feed mixer including an uprigljit ni' ing box having a mixing chamber ther` and a. mixing device within the chamber, a feed box communicating at one end'with the upper portion of the m7 Aing box, having stops adjacent to the mixing box, a feed plate shiftable lengthwise of the feed' box to shift material therefrom into the mixing box, and partition plates removably disposed within the feed box to lseparate the'feed therein, each partition plate bei-ng' movable with the feed toward and engageable with said stops adjacent to the mixing box, to cut off feed thereto.
